Area-based vs tree-centric approaches to mapping forest carbon in Southeast Asian forests from airborne laser scanning data
Abstract Tropical forests are a key component of the global carbon cycle, and mapping their carbon density is essential for understanding human influences on climate and for ecosystem-service-based payments for forest protection. Discrete-return...

Real Time Measurement of Concentration and δ13C-CH4 in Water
Abstract A new, high temporal and spatial resolution, in-situ method for the fast and precise determination of methane (CH4) concentration and its δ13C isotope value (δ13C-CH4) in water was developed. Methane is extracted from water by the...
